Maunsell Forts, North Sea
Offshore of Kent, England, a group of metal structures stand above the water. The Maunsell Army Sea Forts contained radio stations that were designed to warn London citizens of oncoming airstrikes during WWII.
After the Maunsell Forts were decommissioned in the 1950s, they were taken over as “pirate radios” to broadcast music and news without proper licensing. Today, these buildings lay abandoned and decaying.
